Abstract

PURPOSE: To manifacture uniform rolled product through the stable accelerated operation, by computing the forecast for rolling torque under acceleration using the motor torque and r.p.m. of each stand, on purpose to obtain the optimum rate of acceleration for controlling the acceleration at each stand.
CONSTITUTION: The speed of rolling stands 2i, 2j, as the detecting signal of the speed detector 4i, 4j, together with the torque signal of motors 3i, 3j, are inputted to the arithmetic unit 5. The rolling load of each stand is detected by the load cells 6i, 6j; and the output of the load cell 6i together with the torque signal of DC driver 3i, are inputted to the tension controller 7. The speed controllers 8i, 8j, are operated by the instruction sent from the tension controller 7; at the moment when the interstand tension is controlled to a specified range by speed controllers 8i, 8j, the arithmetic unit 5 makes the optimum acceleration pattern for the rolling stands 2i, 2j, and sents it out to speed controllers 8i, 8j, as the reference signal. According to this method, a stable control of the acceleration for all stands can be carried out.
